  2. 21. Post-Glacial History of Sea-Level and Environmental Change in the Southern Baltic Sea

    Author : Marloes Kortekaas; Kvartärgeologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; kartografi; klimatologi; Geofysik; fysisk oceanografi; physical oceanography; meteorology; Sedimentologi; Stratigrafi; Stratigraphy; Baltic Sea; geokemi; Petrologi; mineralogi; geochemistry; mineralogy; Petrology; greigite; mineral magnetics; sea-level changes; Holocene; Littorina transgression; geomorphology; pedology; cartography; climatology; meteorologi; Geophysics; Sedimentology; Optically Stimulated Luminescence OSL ; Fysisk geografi; geomorfologi; marklära; Physical geography;

    Abstract : A new palaeoenvironmental record of the post-glacial history of the southern Baltic Sea (~14 ka to present) is presented. During this period, large water level and salinity changes occurred in the Baltic Basin due to opening and closing of connections to the North Atlantic. READ MORE

  4. 22. Glaciodynamics, Deglacial Landforms and Isostatic Uplift during the last Deglaciation of Norrbotten, Sweden

    Author : Mattias Lindén; Kvartärgeologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Sedimentologi; Sedimentology; Geologi; physical geography; Geology; glaciotectonic; thrust stacking; deforming bed; ribbed moraine; Niemisel moraine; De Geer moraine; isostatic uplift; glaciodynamics; deglaciation; klimatologi; kartografi; marklära; Fysisk geografi; geomorfologi; geomorphology; cartography; climatology; pedology;

    Abstract : The aim of this thesis was to reconstruct the glaciodynamics, deglacial landforms, isostatic uplift and to date the deglaciation. Glaciodynamics and deglacial landforms were focused on to provide a process and depositional model for De Geer moraine and Niemisel moraine and to reveal their internal and spatial relationship, based on detailed sedimentological and structural investigations.

  5. 23. Modeling Carbon and Water Fluxes in European Terrestrial Ecosystems

    Author : Pablo Morales; Institutionen för naturgeografi och ekosystemvetenskap; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; climatology; Fysisk geografi; geomorphology; pedology; cartography; Physical geography; water fluxes; climate change; kartografi; geomorfologi; klimatologi; marklära; carbon fluxes; regional climate models; vegetation dynamics; ecosystem modeling;

    Abstract : The controlling mechanisms and feedbacks between climate, the carbon and water cycling and vegetation in European ecosystems have attracted much attention in recent years but they are still not sufficiently understood. A better understanding of them is necessary to predict how they will be affected by climate change. READ MORE

  6. 24. Mechanisms of below-ground carbon cycling in subarctic ecosystems

    Author : Maria Olsrud; Institutionen för naturgeografi och ekosystemvetenskap; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; cartography; climatology; Fysisk geografi; geomorfologi; marklära; kartografi; klimatologi; pedology; geomorphology; Physical geography; subarctic tundra; phosphorous mobilization; organic acids; open top chamber experiment; 15N natural abundance; Ericoid mycorrhizas; global change; 14C pulse-labelling; Carbon allocation;

    Abstract : Some components of the below-ground carbon (C) cycle in terrestrial ecosystems are still poorly understood. A better understanding will be necessary to predict adequately the impacts of global change factors on C cycling and storage, especially in high-latitude ecosystems, where much of the C is stored below-ground.

  7. 25. U-Pb geochronology of tectonothermal events related to the Rodinia and Gondwana supercontinents -observations from Antarctica and Baltica

    Author : Oskar Paulsson; Berggrundsgeologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; klimatologi; pedology; climatology; Fysisk geografi; geomorfologi; marklära; kartografi; geomorphology; Physical geography; Gondwana; Rodinia; Antarctica; Baltica; Dronning Maud Land; cartography;

    Abstract : This thesis presents data from two areas, Dronning Maud Land, Antarctica, and the Scandinavian Caledonides, Baltica. In addition, a comparative geochronological study is presented. The bedrock of Dronning Maud Land (DML) is dominated by migmatitic gneisses and post-tectonic intrusions. READ MORE
